Im on SH21, just to unlock more, but what exactly do i need to have? Which things i Convert into what? Do i need Houses at all? Can i break the Game, Mines or farms needed?
Those advanced buildings, are there on their own? Or an Upgrade to Current?
Advanced buildings are other buildings converted into them. They can convert back, no cost to resources, with a 5 second “build time” which is both ways after initial conversion, meaning after you have made it you can swap at will as long as you have an active builder available.
In most cases, most people make Alchemy Lab, Hunter’s Lodge, Hero Academy, and Barrcks from Forges.
